FIELD OF THE INVENTION

The invention relates to a butchering process for meat products. More particularly, the invention relates to a butchering process for the chuck portion of a beef carcass.

BACKGROUND OF THE INVENTION

In the United States, the organized grading of cattle and beef has become particularly important in the promotion and marketing of quality products. Administered by the United States Department of Agriculture, the grading system is used to assign a distinct level of quality to cattle carcasses.

Carcass beef grades include a “yield grade” and a “quality grade.” The yield grade, denoted by the numbers 1 through 5, generally refers to the degree of cutability of the carcass and serves as an indicator of the amount of closely trimmed (½ inch fat or less), boneless retail cuts expected to be derived from the major wholesale cuts of the carcass. “Yield Grade 1” represents the highest degree of cutability. The quality grade, on the other hand, separately indicates the palatability of the lean. Carcasses of steers and heifers may be graded as Prime, Choice, Select, Standard, Commercial, Utility, Cutter, and Canner, in descending order of quality; carcasses of cows may receive any of these grades except Prime. Bullock carcasses may be graded as Prime, Choice, Select, Standard, and Utility. Steers are considered male bovines castrated when young and which have not begun to develop the secondary physical characteristics of bulls, while heifers are considered young, such as less than 3 year old immature female bovines that have not developed the physical characteristics typical of cows, e.g., have not borne a calf. Cows are considered female bovines that have developed through reproduction or with age, the physical characteristics typical of mature females, and bullocks are considered young, such as under approximately 24 months of age, male bovines that have developed or begun to develop the secondary physical characteristics of bulls.

The highest quality grade, USDA Prime, is reserved for beef with abundant marbling (defined as flecks of fat within the lean muscle), thus providing a juicy and flavorful meat that also is tender. USDA Prime, for example, may have more than 8% intramuscular fat. Only a small percent of all graded carcass beef qualifies as USDA Prime. As would be expected, Prime beef is favored by hotels and restaurants, is a successful commercial export product from the United States, and also is available through retail sales to discriminating consumers. Because it represents the highest quality, beef certified as USDA Prime commands the highest prices in the market.

The carcass typically refers to both sides of the animal, whereas a side refers to half of the carcass including both a frontquarter and a hindquarter. From the standpoint of profitability the hindquarter cuts of the carcass, which represent about half of a side of a beef carcass, traditionally have been greatest in demand. In particular, the hindquarter includes the full loin with the short loin and sirloin, the round, flank, and kidney knob. Thus, the hindquarter is the source of the well known beef cuts including the top loin steak, T-bone steak, porterhouse steak, tenderloin roast or steak (such as chateaubriand or filet mignon), top sirloin steak, sirloin steak, tenderloin roast or steak, beef tri-tip, round steak, top round roast or steak, and rump roasts.

The frontquarter, which represents the other half of a side of a beef carcass, includes the chuck, rib, plate, brisket and shank, Products typically produced from the frontquarter include cuts such as the rib roast or steak, rib eye roast or steak, back ribs, skirt steak, and whole brisket. The chuck, although used for such cuts as a pot roast (chuck roast), is not considered to be among the wholesale cuts that is most profitable and in demand. Beef from the chuck typically is transformed into lower cost ground beef chuck for example for use in producing ground beef chuck patties.

Once a carcass has been graded as Prime, each of the cuts from the carcass retain that designation. Thus, cuts from both the frontquarter and hindquarter are graded Prime, including the less profitable Prime chuck. There exists a need to make use of the chuck to produce steaks instead of simply being used as roasts or being ground into ground beef chuck. Moreover, there exists a need to make use of the Prime chuck to produce Prime steaks instead of simply being ground into Prime ground beef chuck. Because of the demand for the more costly cuts of Prime beef—which for example restaurants and hotels prefer to offer to customers—the ability to make use of Prime chuck for steaks may lead to enhanced profitability derived from this portion of the carcass. There has been substantial industry interest in enhancing the value of the frontquarter. For example, scientists from the University of Nebraska and the University of Florida even conducted a study for the Cattlemen's Beef Board and analyzed more than 5,500 muscles of the beef chuck and round to assist in developing new beef products. Commercialization of the flat iron steak, a shoulder top blade steak cut from the chuck is said to have resulted from the study. Nevertheless, the chuck is complex because of the number of muscles and associated fibers that do not run in the same direction as each other. Thus, despite the efforts to date as described above, there remains a need for additional methods of producing products from the chuck.

The “fabrication” of the beef carcasses is conducted in mass-production operations by beef packers, who harvest finished cattle purchased from feedlots and create primal, subprimal, and sometimes consumer-ready cuts. The beef then is distributed to purveyors/processors or retailers for further sale. Thus, there is a need for additional methods of producing products from the chuck for use in the mass-production operations.

SUMMARY OF THE INVENTION

The invention relates to a method for mass-production butchering of a beef chuck roll including: locating the anterior side and posterior side of the chuck roll; making a first series of cuts into the chuck roll along lines not intersecting the anterior and posterior sides to form a first set of separate beef portions with increasing weights from initial to final cuts in the first series, each beef portion having a thickness no greater than 1 inch; making a second series of cuts into the chuck roll along lines not intersecting the anterior and posterior sides to form a second set of separate beef portions each having a thickness greater than the thicknesses of the beef portions in the first set.

BRIEF DESCRIPTION OF THE DRAWINGS

Preferred features of the present invention are disclosed in the accompanying drawings, wherein:

FIG. 1 is a perspective view of a beef chuck roll for use with the present invention; and

FIG. 2 is a front view of a beef portion in the second set of beef portions cut from the chuck roll of FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The chuck is generally the shoulder region of the animal, and includes part of the neck and backbone, the first five ribs (U.S. packer/processors typically make the chuck/rib break between the 5th and 6th ribs), as well as portions of the shoulder blade and upper arm. It can weigh over 100 lbs.

Among the cuts derived from the chuck is the chuck roll, which is formed of muscle, fat, and connective tissue and typically weighs between 13 and 21 lbs. In particular, a beef chuck roll may be a generally oblong boneless portion of beef that is derived from a neck off boneless square-cut chuck (square blade chuck). The chuck roll may be produced from the upper portion of the chuck. In one preferred exemplary embodiment, the chuck roll includes the large muscle system that lies beneath the blade bone. The muscle system may be formed of the longissimus dorsi, rhomboideus, spinalis dorsi, complexus, multifidus dorsi, serratus ventralis, subscapularis and splenius. The chuck roll may not include the arm portion, which may be removed by a straight cut for example that is between 0 inch and 3 inches ventral from the longissimus dorsi at the rib end and between 0 inch and 4 inches from the complexus at the neck end. Also removed from the chuck roll may be any cartilages, bone chips, backstrap, trapezius, supraspinatus, intercostal meat (rib fingers), and prescapular lymph gland along with surrounding fat, blood clots, and dark discolored tissue. In alternate exemplary embodiments, the beef chuck roil may be a bone-in cut that includes portions of the blade bone, arm bone and/or backbone.

The chuck roll includes (1) a dorsal side, e.g., located toward the back of the animal, (2) a ventral side, e.g., located toward the belly/bottom of the animal, (3) an anterior side, e.g., toward the front or cranial end of the animal, and (4) a posterior side, e.g., located toward the rear or caudal end of the animal.

In a first exemplary method for butchering a beef chuck roll 10 according to the present invention, suitable for example for use in mass-production butchering, the anterior side or front 12 and posterior side or back 14 of a chuck roll are initially identified. Next, a first series of cuts are made into the chuck roll along lines 16 not intersecting the anterior and posterior sides to form a first set of separate beef portions 18. Preferably, the first series of cuts are made so that each successive beef portion 18 a, 18 b, 18 c has increasing weight. Moreover, in one preferred exemplary embodiment each beef portion 18 a, 18 b, 18 c has a thickness no greater than 1 inch. In one exemplary embodiment, each beef portion 18 a, 18 b, 18 c is about ¾ inch in thickness, as indicated for example by T1 in FIG. 1. In an alternate exemplary embodiment, each beef portion 18 a, 18 b, 18 c has a thickness between 1 inch and 2 inches.

Next, a second series of cuts are made into the chuck roll along lines 20 not intersecting the anterior and posterior sides 12, 14, respectively, to form a second set of separate beef portions 22. In one preferred exemplary embodiment, each of the beef portions in the second set has a thickness greater than the thicknesses of the beef portions in the first set. As shown in FIG. 2, the separate beef portions 22 a, 22 b, 22 c in the second set may each comprise a seam of intramuscular fat 24. Thus, one or more of the beef portions 22 a, 22 b, 22 c in the second set may further be cut proximate the seam to separate each beef portion into two subportions 26, 28. In addition, waste may be removed from at least one of the beef portions in the second set, such as proximate region 30 which may be more tough than desired for use in steaks, so that each of the subportions 26, 28 weighs between 8 oz. and 16 oz. In one exemplary embodiment, each beef portion 22 a, 22 b, 22 c is about 1¼ inch in thickness, as indicated for example by T2 in FIG. 1. The method may further include removing the sinue from at least one of the subportions 26, 28.

In the exemplary preferred embodiment, as much as ¾ of the chuck roll is cut in the first and second series leaving a remaining portion 30 of at least ¼ of the chuck roll. Remaining portion 30 may be further cut into two or more portions, for example proximate the middle thereof from the anterior side 12 to the posterior side 14, thus forming sections suitable for use as pot roasts. Remaining portion 30 also may be sectioned into portions sized for use in beef stew. In some embodiments, remaining portion 30 is not further sectioned, but instead for example may be tied to form a larger pot roast.

In some instances, waste such as undesired muscle, fat, and/or connective tissue is removed from the first set of beef portions 18 so that each portion 18 a, 1 8 b, 18 c weighs between 8 oz. and 16 oz. Also, fat may be removed from at least one of the beef portions of either set 18 or 22.

It should be noted that although each of sets 18, 22 is shown with three portions 16, 20, respectively, this example is non-limiting. Thus, depending on the size of chuck roll 10, other numbers of portions 16, 20 may be cut, such as more than three or less than three portions in either or both of sets 18, 22.

Preferably, chuck roll 10 has abundant marbling and is graded Prime, so that the portions of beef from chuck roll 10 also may be considered as Prime. Also, in preferred embodiments, the portions of beef cut from chuck roll 10 are aged. But in other embodiments, other grades may be used.

In another exemplary embodiment of the present invention, other parts of a chuck are contemplated for use in producing steaks. For example, the neck off the arm chuck also may be used with the “bone in.” Large beef portions or steaks from 14 oz. to 22 oz., and more preferably 16 oz. to 20 oz., are contemplated. Also, the shoulder portion of the chuck may be used for example for minute steaks, sandwich steaks, fry steaks, and steak on a bun. Beef portions of 3 oz. to 4 oz. are contemplated from the shoulder portion.

In accordance with another exemplary method of the present invention, mass production butchering will now be described for a #116A beef check, chuck roll (The Meat Buyer's Guide: Beef, Lamb, Veal, Pork, and Poultry. North American Meat Processors Association; John Wiley & Sons, Inc., New Jersey, 2007).

The #116A beef chuck, chuck roll is boneless. It is derived from a neck-off boneless square cut chuck. This cut contains muscles including the rhomboideus, multifidus dorsi, complexus, longissimus dorsi, spinalis dorsi, and serratus ventralis.

Initially, the #116A beef chuck, chuck roll is split anterior to and generally parallel to the first rib, and preferably is split about 1.5 inches anterior to the first rib (as used herein, the first rib is the rib closest to the humerus, e.g., proximate the neck portion). This initial sectioning of the chuck roll separates the neck portion (the anterior portion of the chuck roll) from the remainder of the chuck roll.

Next, with the neck portion removed, a natural seam in the remainder of the chuck roll is followed and the remainder is sectioned into two portions: (1) a first portion with the rhomboideus, the spinalis dorsi, and the serratus ventralis, and (2) a second portion the multifidus dorsi, the complexus, and the longissimus dorsi. In a preferred exemplary embodiment, the muscles in each of the two portions are separated together, e.g., in the first portion the rhomboideus, the spinalis dorsi, and the serratus ventralis are connected, while in the second portion the multifidus dorsi, the complexus, and the longissimus dorsi are connected.

The above-mentioned natural seam may be a seam of fat therebetween that may be intermuscular fat or intramuscular fat.

The first portion preferably is then sectioned so that the rhomboideus is removed because of its undesired toughness. In addition, the spinalis dorsi is removed (“squaring up” the serratus ventralis) along with fat, sinue, and connective tissue, e.g., the serratus ventralis is trimmed to expose the lean. After this sectioning of the first portion, a denuded serratus ventralis remains. The serratus ventralis then is cut into separate portions which preferably are suitably sized for steaks. In an exemplary embodiment, the steaks formed from the serratus ventralis may be between about 1 inch and about 1¼ inch in thickness, and preferably about 1 inch in thickness.

In an alternate embodiment, the serratus ventralis cut according to the above-described method may not be sliced into individual steaks, but instead may be used as a London Broil, pot roast, or for other purposes.

In yet another alternate embodiment, the first portion is sectioned so that the spinalis dorsi is removed but theserratus ventralis and at least a portion of the rhomboideus are left connected. Then, the first portion with theserratus ventralis and rhomboideus is cut into separate portions which preferably are suitably sized for steaks, the individual steaks having portions of one or both of theserratus ventralis and rhomboideus. In an exemplary embodiment, at least about 20 wt % of the rhomboideus is cut from the first portion prior to cutting the first portion into steaks. In another exemplary embodiment, between about 10% and about 90% of the rhomboideus is cut from the first portion prior to cutting the first portion into steaks.

Next, the second portion with the multifidus dorsi, the complexus, and the longissimus dorsi is cut into steaks, with fat, sinue, and connective tissue again being removed to expose the lean. In an exemplary preferred embodiment, the individual steaks each include portions of the multifidus dorsi, complexus, and longissimus dorsi muscles. In an exemplary embodiment, the steaks formed from the second portion may be between about 1¼ inch and about 1¾ inch in thickness.

After steaks are cut from the first and second portions, preferably the steaks are needled. In particular, jaccarding (also known as needling and blade tenderizing) is known as a technique for piercing meat for tenderizing. A double jaccarding machine, for example, needles a piece of meat on both sides thereof. Although jaccarding is known in mass production butchering, jaccarding typically is employed in such operations to larger cuts of meat not individual steaks. In an exemplary embodiment of the present invention, the steaks cut from theserratus ventralis are individually needled on each side thereof. While the needle marks may be visible in meat in the raw state, advantageously the marks are not necessarily visible in the meat once cooked.

In some embodiments, raw steaks produced from the first and/or second portions of the chuck roll may be tied with butcher's twine for shaping and compacting, which also provides an attractive presentation to the cuts. The tying, for example, may permit a raw steak produced from the first and/or second portion of the chuck roll to have a generally circular or otherwise arcuate shape. Alternatively, such a shape may be achieved by clamping the raw steak using pins.

Also, in some embodiments, raw steaks produced from the first and/or second portions of the chuck roll may be wrapped in fat, bacon, or prosciutto.

Moreover, in some embodiments, the neck portion initially separated from the chuck roll may be ground to produce ground beef.

In some embodiments, the first portion and/or the second portion may be thinly sliced into pieces with a thickness between about 2 mm and about 4 mm. Such thin slices are known as “shabu-shabu” (which then may be cooked for example in hot water or broth). In one exemplary embodiment, theserratus ventralis is chilled to facilitate slicing, and then thinly sliced instead of being cut entirely into steaks with substantially greater thickness.

The chuck roll, portions thereof, and steaks cut therefrom according to an exemplary embodiment may be injected with salt(s) such as sodium chloride, calcium chloride, and/or sodium phosphate in solution (i.e., in a saline solution) and/or other enhancers for enhanced moisture and enhanced flavor. In some exemplary embodiments, the chuck roll, portions thereof, and steaks cut therefrom may be pounded.

In some exemplary embodiments, the chuck roll, portions thereof, and steaks cut therefrom may be marinated.

In yet another exemplary embodiment, with the neck portion removed, a natural seam in the remainder of the chuck roll is followed and the remainder is sectioned into two portions: (1) a first portion with the rhomboideus and the serratus ventralis, and (2) a second portion the multifidus dorsi, the complexus, the longissimus dorsi, and the spinalis dorsi.

It should be emphasized that although the sectioning of a #116A beef chuck, chuck roll has been described above, other forms of a beef chuck may be used. For example, a #116D beef chuck, chuck eye roll includes the multifidus dorsi, complexus, longissimus dorsi, and spinalis dorsi. (The Meat Buyer's Guide: Beef, Lamb, Veal, Pork, and Poultry. North American Meat Processors Association; John Wiley & Sons, Inc., New Jersey, 2007). Thus, according to another aspect, the above-described methods may be used with a #116D product while not requiring removal or partial removal of the rhomboideus (which is not included in a #116D product).

The first portion and/or second portion in some embodiments may be used in its entirety, or any portion thereof, for example as a roast, which also for example may be tied.

Moreover, the beef chucks described above may be aged before being cut or after being cut into first and second portions and/or individual steaks therefrom.

While various descriptions of the present invention are described above, it should be understood that the various features can be used singly or in any combination thereof. Therefore, this invention is not to be limited to only the specifically preferred embodiments depicted herein.

Further, it should be understood that variations and modifications within the spirit and scope of the invention may occur to those skilled in the art to which the invention pertains. Accordingly, all expedient modifications readily attainable by one versed in the art from the disclosure set forth herein that are within the scope and spirit of the present invention are to be included as further embodiments of the present invention.
